Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to an automatic telescopic material rake and conveyor integrated machine. Background Art

[0002] The rolling rake loader is a machine that loads materials with a rolling loading rake. Usually, the operating radius of the rake loader is fixed. After each work within the operating radius is completed, the rake loader needs to be moved to transfer to complete the loading of materials outside the operating radius. This not only makes the movement, installation and commissioning of the equipment very troublesome, but also delays time and reduces the operating efficiency.

[0003] Therefore, how to solve the above problems has become the focus of research in this field. Summary of the invention

[0004] The object of the present invention is to provide an automatic telescopic material rake and conveyor integrated machine to solve the problems of the prior art.

[0009] And a conveying mechanism assembly connected between the rake material machine and the conveyor, which includes a plurality of conveyor belts, and the conveyor belts at each level can be telescopically adjusted along the length direction of the conveyor belts.

[0010] Furthermore, the rake material machine includes a digging hopper, a transmission roller, a transmission motor, a material receiving bin and a first-stage conveyor belt. The digging hopper is circumferentially arranged on the outer peripheral surface of the transmission roller, the transmission motor is transmission-connected to the transmission roller, and the material receiving bin is arranged adjacent to one side of the transmission roller for receiving the material in the digging hopper.

[0011] Furthermore, in the several levels of conveyor belts, each level of the conveyor belt includes a conveyor belt body, a support frame for supporting the conveyor belt body, and a transmission rack arranged on the lower bottom surface of the support frame and arranged along the length direction of the support frame. Except for the first level of conveyor belt, each subsequent level of conveyor belt is provided with a telescopic guide rail and a telescopic gear on the support frame. Between two adjacent levels of conveyor belts, the support frame of the previous level conveyor belt is installed in the telescopic guide rail of the next level conveyor belt, and the transmission rack of the previous level conveyor belt is meshed with the transmission gear of the next level conveyor belt.

[0012] Furthermore, the support frame is provided with a positioning guide wheel, and the positioning guide wheel is installed in the telescopic guide rail.

[0013] Furthermore, among the several levels of conveyor belts, the first two levels of conveyor belts are respectively a primary conveyor belt and a secondary conveyor belt. When the primary conveyor belt and the secondary conveyor belt are at their maximum extended lengths, the primary conveyor belt can rotate along a vertical plane relative to the secondary conveyor belt.

[0014] Furthermore, a low-position limiter is provided at the front end of the primary conveyor belt to prevent the primary conveyor belt from touching the ground during rotation.

[0017] Furthermore, an adjustable counterweight is provided at one end of the upper housing opposite to the conveying mechanism assembly, and the weight of the counterweight is adjusted according to the telescopic length of the conveying mechanism assembly.

[0018] Furthermore, a discharging conveyor belt is arranged in the lower casing.

[0019] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0020] The present invention adopts a conveying mechanism assembly composed of a multi-stage retractable conveyor belt, and connects the rake machine and the conveyor through the conveying mechanism assembly, so that the operating radius of the equipment can be changed by adjusting the length of the conveying mechanism assembly, and the operating direction of the equipment can be changed by coordinating the rotation of the upper casing, so that the equipment does not need to be frequently transferred during operation, which greatly saves working time and improves work efficiency.
